i40e: Remove queue tracking fields from i40e_adminq_ring
Fields 'head', 'tail', 'len', 'bah' and 'bal' in i40e_adminq_ring are used to store register offsets. These offsets are initialized and remains constant so there is no need to store them in the i40e_adminq_ring structure. Remove these fields from i40e_adminq_ring and use register offset constants instead. Remove i40e_adminq_init_regs() that originally stores these constants into these fields. Finally improve i40e_check_asq_alive() that assumes that non-zero value of hw->aq.asq.len indicates fully initialized AdminQ send queue. Replace it by check for non-zero value of field hw->aq.asq.count that is non-zero when the sending queue is initialized and is zeroed during shutdown of the queue.
